摘要
目的:通过对灰毡毛忍冬褐斑病的发生规律和药剂防治研究,为综合防治提供依据。方法:田间调查和药剂防治试验。结果:褐斑病由Cercospora sp.引起,4月上中旬开始发病、7—8月为发病盛期;发病情况与海拔、土壤有机质含量、土壤速效磷含量、土壤速效钾含量和栽培品种相关;10%苯醚甲环唑水分散粒剂1 500倍液防治效果最好,50%福美双可湿性粉剂800倍液、70%代森锰锌可湿性粉剂800倍液也具有较好防治效果。结论:适当的农业防治和化学防治方法能有效防治灰毡毛忍冬褐斑病。
] Objective： To study the occurrence of Cercospora leaf spot of Lonicera macrathoides and fungicides control method, so as to provide scientific basis for its integrated pests management （IPM）. Method： The field investigation and the field controlling trial were carried out for the research. Result： Cercospora leaf spot was caused by C. rhamni. There was obvious relationship between the damage rate and the altitude, soil organic matter, available K, available P as well as variety. The controlling effect of 10% difeno- conazole WG was the highest. 50% Thiram WP, 70% Mancozeb WP also had well controlling effect. Conclusion： Cercospora leaf spot of L. macrathoides could be controlled by suitability agricultural and chemical controls .
